Abstract
The research entitled “The Doctrinal Transformations of the Egyptian Army after the British Expulsion” deals with the definition of the developments that Egypt witnessed in the wake of the British evacuation from its lands in 1954, and its impact on the military doctrine of the Egyptian army, represented by the tripartite aggression in 1956, the Yemen war in 1961, and the setback of June in 1967, As each of these events has contributed to strengthening or adding a new belief in which the sons of the Egyptian military establishment believed and fought for it.
